Appeal No. 2001-0250 Page 17
Application No. 08/283,074
pertinent part the following limitations: "a processor means
coupled to said plurality of pressure-wave-sensing transducers
for processing said first and second transduced signals to
provide said output signal characteristic of said confined
volume geometry, wherein said confined volume is characterized
by cross-sectional area as a function of distance from said
opening in said confined volume and said processor means
provides as said output signal an area signal that is
characteristic of cross-sectional area of said confined volume
as a function of distance from said opening in said confined
volume ...."
Further similarly, claims 81-83, 89, and 90, by virtue of
their dependence from claim 80, specify in pertinent part the
following limitations: "a processor means coupled to said
plurality of pressure-wave-sensing transducers for processing
said first and second transduced signals produced in response
to the incident wave, the reflected wave and any reflected
wave from the second end to provide a signal representative of
an impulse response of the geometry and to provide said output
signal characteristic of said confined volume geometry,
